The spate of accidents on infrastructure sites in the city continues.

A 21-year-old construction worker died at the Versova-Andheri-Ghatkopar Metro project construction site in Andheri on Thursday after he fell from a height of 18m.

Three people have died in the last week while working on projects taken up by the Mumbai Metropolitan Region Development Authority. On July 1, two workers were killed in an accident on a Monorail site at Chembur.

The victim, Banvarilal Ram, died after he sustained severe injuries on his head, after falling from the bridge, which was under construction at JP Road near Navrang Cinema. The injured worker was rushed to Cooper hospital in Vile Parle, where he was declared dead.

The police said the worker died because of negligence on the part of the construction contractor with regards to the safety measures. “The contractor, Dhanukumar Ram, 28, has been booked under IPC 304A (causing death by negligence). He is currently out of town and will be arrested as soon as he is back,” said police sub-inspector, Prakash Shetye from DN Nagar police station.

Mumbai Metro One Pvt Ltd, which is building the project, claimed that the accident took place because of the worker’s negligence. “The construction work is being carried out under a strict safety regime. The worker failed to hook his safety line at the time of the fall,” MMOPL said in a statement.

MMOPL claimed that the worker was provided with safety gear, which includes a safety helmet, boots and jacket.

MMRDA had called for a review of safety measures from contractors after the July 1 Monorail accident.

Eight people have lost their lives because of accidents on Metro or Monorail sites in the last three years.
